This part of IS0 9974 specifies dimensions for ports with IS0 261 threads and elastomeric (type E) or metal-tometal ítype BI sealing for general use and in fluid power applications with the stud ends detailed in IS0 9974-2 and IS0 9974-3. It also specifies test methods and the designation of these ports.
Ports in accordance with this part of IS0 9974 may be used at working pressures up to 63 MPa (630 bar 1) ) . The permissible working pressure depends upon the port size, materials, design, working conditions, application, etc.
For threaded ports and stud ends specified in new designs in hydraulic fluid power applications, only IS0 6149 is to be used. Threaded ports and stud ends in accordance with IS0 1179, IS0 9974 and IS0 11926 are not to be used for new designs in hydraulic fluid power applications.
